I heard Trane has fixed some of the problems it was having. A GC here told me it’s been about 5 years now since it’s been corrected and he has been using them again.
Carrier is what I’ve had in most of my houses. I honestly don’t know what I have in my current house, I’d have to go look.
The old ones should last around twenty years. My fear is the NEW models not living up to their reputations. Ours are Tranes. The one that went out was installed in 1999, it was repaired yesterday but the guy thinks it’ll only last a few more months.
